Abstract (en)
An electric motor (1) includes a rotor (2) including a first rotor end (21a) and a second rotor end (21b), and a stator (3) including a first stator end (31a) and a second stator end (31b). The first rotor end (21a) is located apart from the first stator end (31a) toward the first side. The second rotor end (21b) is located apart from the second stator end (31b) toward the first side. The relationship between the distances D1 and D2 satisfies D1 > D2 ≥ 0, where D1 is a distance from a permanent magnet (220) to a first end plate (27a), and D2 is a distance from the permanent magnet (220) to a second end plate (27b). The thickness of each of a plurality of electrical steel sheets (201) is not less than 0.1 mm and not more than 0.25 mm.
